Scientists finally uncover what causes ice to be slippery
Scientists have solved the long-standing mystery of why ice remains slippery even at extremely cold temperatures by showing through molecular simulations that sliding causes local breakdown of ice's crystal structure, forming a disordered, water-like layer that facilitates slipperiness without the need for melting. This challenges previous theories that relied on pressure melting or frictional heating, highlighting that motion-induced amorphization is the key factor in ice's slipperiness.
